Hi Bruce,
1. Renamed Prepar3d.cfg but no difference.
I'm puzzled by seeing from within the Rift, on my left a big banner with "Waiting for Simulator" on it, in brown and therefore inactive, while to my right I have a window which is active, showing P3D, 2 inches wide on a black background.
i.e. Waiting for Simulator on one side and a tiny but flyable P3D on the other.
2. After the above I disconnected the Triplehead hardware once again, searched the computer for any Matrox entries and deleted them. There was no actual Matrox application. I rebooted into one 22" monitor, but again there was no difference, except that apart from what you have seen in the posted images I now have in addition, a round magnifier which I can move around and enlarge with my bound button .
Next suggestion Please!
Jim
